Hi:
When I try to upgrade Eric 6 from 19.8 to 19.9 on my macos, this exception is raised:
Traceback (most recent call last):
File "./install.py", line 2135, in <module>
main(sys.argv)
File "./install.py", line 2105, in main
res = installEric()
File "./install.py", line 1010, in installEric
createMacAppBundle(cfg['ericDir'])
File "./install.py", line 1226, in createMacAppBundle
os.symlink(macPythonExe, starter)
FileNotFoundError: [Errno 2] No such file or directory: '/opt/local/Library/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python' -> '/Applications/eric6.app/Contents/MacOS/eric'
After debugging install.py, I have found a bug in line 1212 to 1214:
for directory in directories:
if not os.path.exists(directory):
os.makedirs(directory)
This loop is checking the existence of the keys in dictionary `directories` instead of checking the paths (values) in this dictionary.
I think that it should be:
for directory in directories.values():
if not os.path.exists(directory):
os.makedirs(directory)
or:
for directory in directories:
if not os.path.exists(directories[directory]):
os.makedirs(directories[directory])
I have checked the first alternative (with `directories.values()`) and works on my system.
I hope this will be useful for you. Thanks.
